多联式热泵/热管复合式空气源热泵实验研究

Experimental study on multi-type heat pump/heat pipe composite air source heat pump

提出了多联式热泵/热管复合式空气源热泵的循环原理,基于3HP压缩机研制出一套样机进行测试,室内机为6台串联。考查不同工况下系统的制热性能,研究热管温度分布及启动过程特性,多个室内机的温度分布状况,比较热管内充注R134a和水的运行特征,为开拓新型的热泵采暖装置提供参考。

The circulation principle of multiple heat pump/heat pipe air source heat pump was put forward.A prototype was developed based on 3 HP compressor and the indoor unit was 6 series.The heating performance of the system under different working conditions were carefully examined,the heat pipe temperature distribution,starting-up process characteristics and the temperature distribution of multiple indoor units were also studied.At last,the charging characteristics of R134a and water in the heat pipe was compared.This research can provide reference for the development of a new type of heat pump heating device.
